DETAGHAIBLE MANGLE.

Specication ef Letters Patent. Patented Nov. 29, 1.921.

Application filed September 13, 1920. Serial No. 409,764.

Worth, in the county of Tarrant and StateV of Texas, have invented certain new and useful Improvements in Detachable Mangles, of which the following is a specification.

Our invention relates to mangles for use with washing machines and more particu.- larly to detachable-mangles which can be used with various types of driving heads; and the object is to provide mangles which are simple in construction an'd operation and.

-which'will be highly eficient in ironin the goods and to provide a simple means of eating the mangle and maintaining a steady or substantially uniform temperature during operation and which can be easily attached to a driving head and easily detached therefrom. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed outin the claim.

Reference is had to the accompanying drawings which form a part of this application.

Figure l is a front elevation of the improved mangle, showing the same attached to a wringer driving head. Fig. 2 an end elevation, partly in section and partstbroken and other parts omitted.. Fig. 3 is a broken vertical section, Figs. 2 and 3 being enlarged to show more clearly the construction ofthe several parts.

Similar characters of reference are used to indicate the same parts throughout the several views.

Our invention is illustrated with one of the types of driving heads of wringer attachments. The wringer or driving head 1 is provided with .the'usual power connecting shaft coupling 2. The mangle is provided with a frame having upright members 3, U- shaped cap member 5 attached to uprights 3 and 4, and side slabs or bars 6 attached to the members 3 and 4. The members 3 'and 4 are provided with inwardly projecting flanges to which the members 5 and 6 are attached.

The means for ironing the goods consists of a revolving drum 7 which is loosely mountends for admission of air. Means are provided for heating the drum 7. The pipe 8 1s fixed agalnst rotation by a collar 10 which is rigid with the pipe 8 and is prevented from .turning by dowel pins 11 which are r1g1d 1n the upright 3. The pipe 8 has'perforatlo'ns 12 for escape 'of gas to be burned in the drum 7. The pipe 8 is provided with an air mixer 13 which is adjustable onthe pipe 8 and may be held at different adjustments by a set screw 14. The gas is -admitted through a nipple 15 and the amount of gas admitted may be regulated by a needle valve 16. The gas is lighted at the point 17 and the force of the air causes the heat and iame to be directed toward the opposite end of the drum or toward the driving head 1.

The mangle is provided with a power shaft 18 which is journaled in stationary bearings 19 whichare mounted in the uprights 3 and 4 and supported and held in place by the rods 20 with their nuts 21. The side bars 6 are attached to uprights 3 and 4 by the bolts 20and bolts 22 with nuts 23.

The pipe 8 is mounted in movable bearings 24. These bearings are vertically movable in the uprights 3 and 4 and rest on springs Voperating elements, the drum 7 may be pressedmore or less on the. goods to be passed between the drum 7 and Athe co erating drum 27 which is carried by t e power shaft 18. The ironing drum 7 is thus held suspended between the springs 25 and 25 and in the Vbearings 24 which are vertically movable in the uprights 3 and 4. The ironing drum 'is thus held yieldingly on the goods which are passing through the mangle.

The pressing drum 27 is prepared byplacing a felt covering 28 next' to the shaft 18 and then'winding a sheet of cloth on the felt 28 and the cloth is wound or wrapped.l on the drum in convolute form 11T-til the lrequired thickness is attained to form a suitable pad which is more or less yielding. The

shaft 18 is driven by the gearing of the driving head l. The mangle is bolted or riveted to the head l by bolts or rivets passing through the upright 4 and through the adjacent frame piece of the driving head. An inclined table or receiving plate 29 is attached to the mangle. frame to receive the goods which are going to the pressing members of the manglel and inclined discharge plate 30 is attached to the mangle frame from which the goods may be taken. Various changes in the sizes, proportions, construction and arrangement of the several parts may be made without departing from our invention.

What we claim, is,-

The combination of a driving head and a mangle detachably connected to said head,

said mangle having a revolving drum pad f driven by said head, a hollow pipe extendin through said mangle, vertically movab e bearings for said hollow pipe, means for adjusting and applying pressure to said bearings to hold said pipe at dili'erent adf justments relative to said drum, a hollow ironing drum mounted loosely on said pipe and adapted to be driven by friction of goods passing between said drum pad and said ironing drum, said pipe having perforations for directing gas jets within said drum, and means for supplying gas and air through said hollow pipe for heating said drum.

In testimony whereof,l we set our hands, this 2nd day of September, 1920.'
